. ROOFING-TILE.

To all whom it may concern:

Be it known that I, RICHARD D. Wx'rsoN,

a citizen of the United States, residing at Rochester, county ofOakland, State of Michigan, have'invented a certain new and usefulImprovement in Roofing-Tiles, and declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the' art to which it pertains to make and use the same,reference being had to the accompanying drawings,

' which form a part of this specification.

This invention relates to roofing tile.

It has for its object an improved tile to be used for covering roofs,side walls and m similar locations in the construction of build-- ings.

Inthe drawing,Figure'1, is a longitu diual section of a number of tilesas they appear in place on the roof slats. Fig. 2, is

longitudinal sectional line a, a, of Fig. 2.-

The tile 1, consists of a rectangular block of artificial stonematerial, preferably composition made from Portland cement and sand, andis provided on the upper side 80 with convex flutings which broaden atthe base or exposed end of the tile. and narrow nearly to a point at theto or covered end bf the tile. Between the utings 2, 3, is a tabularplane 4, which is a plane surface on 85 the upper or partly exposed sideof the tile.

On the under side the 'end 51, of the tile has its lower face inclinedto the upper face with the thinner edge toward the-covered. end of I thetile and with the thick edge or the thick- 40 ened portion intermediatethe two endsof the tile at the line 6, 6. Alon this line the drop fromthe lower face oft e tile is sub stantially equal to the thickness ofthe upper edge of the tile so that the body of the-tile from the upperedge to the lower edge con- 2 stitutes a ock of substantially uniformthickness with a thickened intermediate portion narrowingfrom the innerline 6, 6 toward'the u per end.

Opposite "t e convexity 2, 3, are cavities 2 3, which rise above thegeneral under sur-' I face of the tile. Between the cavities 2, 3*,

is fastened and brin of the over-lying tlle into close contactthroughout its extent with the covered upper is 'a rectangular cavity 7,extendin deep enou h in the body of the idle to orm a cham er for thereception of nail-heads which are driven through the nail-holes 8, inthe edge of the under-lying tile. The cavity 7, extends in longitudinallength under the tile sufliciently to cover the two nail-heads ofa'n-under-lving tile and sufficiently wide to cover the four nail-headsof the two underlying tile, and the use of this cavity avoids thenecessity of drivin the nails entirely home or setting the heads downclose to the tile body and consequently avoids the liability of breakingor cracking the tile by driving the nail-heads home. The inclinedunspeeincation of Letters Patent. Patented J an. 11,1910. Applicationfiled August 8, 1908. Serial No. 448,584. i

der surface of the upper portion of the tile brings that face of thetile into close contact with the roof boards 9, upon which the tile theunder-lying face face of the under-lying tile next adjacent to it, andprevents the liability of breaking the tile when pressure is exerted onits upper surface by walking thereon or placin scaffoldin orladders'upon or against this portion 0 the tile.

WhatIclaim is: l. A- tile having its exposed face inclined to thecentral plane thereof, the inclination being continuous from one end tothe other, and this surface having tapering convex flutings the entirelength thereof, and having its under face terraced transverselyintermediate the ends thereof, one of the sections thus constitutedbeing plane and adapted to lie in intimate contact with the roof, andthe other section having truncated concaved flutings adapted to engageover thoselpor-' tions of the convexed flutings on the ex osed surfaceof the adjacent tileimmediately therebeneath, and having between saidtrun-' cated flutings a cavity for covering nail heads projecting abovethe adjacent surface scribed.

2.A generally wedge shaped tile, havingouter surface being provided with'longitudinally extending convex flutings complemenof an underlyingtile, substantially as de tarily located with respect to similar thoughabbreviated concave flutings in one enci of the under surface thereof,and the fluted portions of'the under surface having between them acavity adapted to cover nail heads projecting above the surface of anunderlying tile, emi the opposite end cf the under surface from thatwherein said concave flutings ere ie-ceteci being plane and adapted toeeem'? lie in intimate contact with the roof, substentially asdescribed. 1 In testimony whereof, I sign this specification in thepresence of two witnesses.
